Diving the Similans: Things on a Wreck

Page copy protected against web site content infringement by Copyscape

Our last dive in the Similans was at Boonsung Wreck. It used to be a whole boat at the bottom of the sea, but the tsunami lifted it up and smashed it into four big pieces. Ironically, this makes for richer marine life as there’s more space for coral to grow and therefore more places for fish to hide and spawn. Among which were these bored, listless looking longfin bannerfish mooching about the place.

There were quite a few moray eels and here was one of the few blackspotted morays I’ve seen. It wasn’t too pleased with its hole because soon after I took this picture, it departed and tried to fight a white eye moray for space but sadly was soon defeated and had to go back to its lousy old hole. Poor guy.

Then there were goby shrimp and their shrimp gobies. It’s cute how all the shrimp does is shovel gravel out of the hole. Talk about a menial task. The goby just guards the hole and darts in at the first sign of trouble. The shrimp never shovels past the middle of the goby’s body. It was so hard to get close enough to take a good picture. This is the best I got.

Then there were these two lovebird cuttlefish who stuck together despite showing their alarm colours. I think there were too many divers hovering over them and no crevices big enough for them to hide in.

Last of all was the only set of nudibranch eggs I saw on the trip. It was funny how there weren’t a huge number of nudibranchs in the Similans. The ones I saw were the rather common and boring ones, so it was such a treat to see the ribbony sheets of eggs. See how each pink dot is an egg? I wonder how these things survive without being eaten by predators, they’re so obvious. Maybe they’re poisonous to most fish.

Boonsung Wreck was a nice easy wreck to dive at. While the viz wasn’t the best, I liked how there was stuff both on the wreck and around it. It was a relaxing end to the diving.
